Find an equation of the line that has a y-intercept of -2 and is perpendicular to the graph of 3x+6y=2

Answers

To do that u need to solve the equation for y
First move the 3x over to get

6y= -3x + 2

Now solve for y by divided by 6

Y= -3/6x + 2/6

A line perpendicular to this equation would have a slope that is the opposite reciprocal, so flip the -3/6 and change the sign

This gives u 6/3 which simplifies to two

The new equation of the line would be y= 2x - 2

In triangle ABC, the measure of angle A is , the measure of angle B is , and the measure of angle C is . What is the combined measure of the three angles?

Answers

Final answer:

The combined measure of the three angles in triangle ABC is angle A + angle B + angle C degrees.

Explanation:

The combined measure of the three angles in triangle ABC can be found by summing the measures of angle A, angle B, and angle C.

So, the combined measure of the three angles is angle A + angle B + angle C = angle A + angle B + angle C degrees.

For example, if angle A = 40 degrees, angle B = 60 degrees, and angle C = 80 degrees, then the combined measure of the three angles would be:

40 + 60 + 80 = 180 degrees.

A bucket holds c liters of water, but a jar holds 8 liters less. How many times as much water can the bucket hold as the jar?

Answers

The ratio representing how many times as much water the bucket can hold as the jar is [tex]\frac{c}{c-8}[/tex], where c is the capacity of the bucket in liters.

If a bucket holds c liters of water and a jar holds 8 liters less than the bucket, then the jar holds c - 8 liters of water. To find how many times as much water the bucket can hold as the jar, we divide the bucket's capacity by the jar's capacity. This gives us the ratio of the bucket's capacity to the jar's capacity, which is [tex]\frac{c}{c-8}[/tex].

A student answers
90%
of the questions on a math exam correctly. If
sheshe
answers
27
questions correctly, how many questions are on the exam?

Answers

So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27

To find the number of questions in the exam, make an equation
(90% = [tex] \frac{90}{100} [/tex] = 0.9)
[tex] \frac{90}{100} [/tex] = [tex] \frac{27}{x} [/tex]
cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer
[tex] \frac{90x}{90} = \frac{2700}{90} [/tex]
90 and 90 cancels out
x = 30
So your final answer will be, there were 30 questions in the exam paper.

Final answer:

To find the total number of questions on the exam, set up a proportion 27 / x = 90% / 100%. Solve for x to find that there are 30 questions on the exam.

Explanation:

To find the total number of questions on the exam, we can set up a proportion. Let's represent the total number of questions on the exam as x.

The proportion would be:

Correctly Answered Questions / Total Questions = Percentage Correct

Substituting the given values:

27 / x = 90% / 100%

Cross multiplying:

27 * 100% = x * 90%

27 = 0.9x

Dividing both sides by 0.9:

x = 27 / 0.9

x = 30

Therefore, there are 30 questions on the exam.

A bag contains 20 marbles of the same size that are blue, green, and red. The probability of picking a blue marble is 20%. The probability of picking a green marble is 50%. Determine the probability of picking a red marble from the bag and then classify the probability of picking a red marble as likely or not likely to occur.

Answers

there are 10 green and 4 blue which give you 6 red. so 30% and not as likely as green.

Hello!!

This is the correct answer.

Probability (Blue Marble) = 20%

Probability (Green Marble) = 50%

Probability (Red Marble) = ?

20% - 50% = 30%

The probability of picking a red marble from the bag is 30%.

Likely is defined as 50% so in this case, the probability of picking a red marble is not likely.

Hope this helps!!!!

Answer:

Area of cross section is 104 [tex]\:inche^2[/tex]

Step-by-step explanation:

Given Dimensions of Rectangular prism are Length = 5 inches, Width = 12 inches and Height = 8 inches.

The shape of the cross section that is perpendicular to the base and created by slicing the prism through diagonals of top and bottom is Rectangle.

Length of rectangle = Length of diagonal of base & top = 13 inches

Width of Rectangle = Height of Prism = 8 inches

Area of Cross Sectional Rectangle = Length × Width

= 13 × 8

= 104 [tex]\:inche^2[/tex]

Therefore, Area of cross section is 104 [tex]\:inche^2[/tex]

5y + 5 - 5 = 30 - 5
5y = 25

5y/5 = 25/5
y = 5

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, h(x) = -7x and h(x) = 63.

∴ We can equate these two functions as h(x) = h(x) which is,

- 7x = 63.

- x = 63/7.

Answers

11 * 10^21 is not in scientific notation.

Scientific notation requires that the digits part is greater than zero and less than 10 (it cannot be 10).

So, to put that number in scientific notation 11 must be converted to 1.1*10 and 11 * 10^21 is 1.1 * 10 * 10^21 = 1.1 * 10^22.

Note tha 11 * 10^21 is the same that 1.1 * 10^22 but the last is in scientific notation while the former is not.

Marlene rides her bicycle to her friend Jon's house and returns home by the same route. Marlene rides her bike at constant speeds of 6 mph on level ground, 4 mph when going uphill and 12 mph when going downhill. If her total time riding was 2 hours, how far is it to Jon's house?

Answers

x = level ground

y = hills

x/6 +y/4 +y/12 + x/6 = 2 hours

multiply everything by 12 to get rid of the denominators:

equation becomes 2x +3y +y +2x = 24

combine like terms:

4x +4y = 24

divide everything by 4

f +h = 6 miles to Jon's house

Jon's house is 6 miles further away from Marlene's house.

Given that:

Speed on level ground is 6 mph

Speed on uphills is 4 mph

Speed on downhills is 12 mph

Let there are x miles level ground and y miles hills(either up or low, which while returning to home will serve as low or up respectively) in the route, then the whole route's length is x + y miles.

Since time taken = distance/speed , thus we have:

[tex]2 = \dfrac{x}{6} + \dfrac{y}{4} + \dfrac{x}{6} + \dfrac{y}{12}\\\\\text{Multiplying 12 on both sides}\\\\24 = 4x + 4y\\6 = x + y[/tex]

Since x + y denotes the length of the whole route(one sided), thus, Jon's house is 6 miles further away from Marlene's house.
